세포분열 과정에 대한 분자수준에서의 본격적인 연구는 1980 년대 후반에 개구리 난모세포(oocyte)의 분열에 대한 연구, 효모의 여러 세포성장이나 방사선 돌연변이체(radiation mutant)의 특정화, 및 종양억제인자(tumor supperessor)인 Rb의 연구를 통하여 활발해지기 시작하였다. 1990 년대에 들어 더욱 자세히 밝혀지기 시작한 세포분열조절 기작에 따르면, 작은 세포성장 조절인자가 세포성장 조절기능을 통하여 세포의 성장, 분화, 발생, 노화, 세포소멸(apoptosis) 등을 중심적으로 조절하는 것으로 밝혀졌다. 이 연구의 결과들은 이미 여러 질병의 병리학적 현상들을 좀더 정확히 이해하는데 큰 도움을 주게 되었다. 그 대표적인 예가 암이다. 정상세포가 암세포로 변형되는 과정에서 세포성장 조절이 그 기능을 상실할 때가 많이 발견되었다. 암세포들을 분석한 결과, 세포성장 조절인자의 활성이 정상과 다른 경우가 많이 나타났고, 특히 이 중에는 암 병리학에 있어서 가장 문제가 되고 있는 침습(invasion)/전이(metastasis)와 깊은 상관관계를 보여 주는 경우도 있다. 또한, 형질전환 동물을 이용하여 세포성장을 조절하는 요소들의 과발현(overexpression) 또는 녹-아웃(knock-out)을 유도하면 이들 실험동물에 암이 유발된다는 사실로 부터도 비정상적인 세포주기조절(cell cycle deregulation)이 암을 유발하는 직접적인 요인이 된다는 것이 입증되고 있다.Molecular research into cell division processes in the late 1980s led to the study of the oocyte division of frogs, the growth of various cells in yeast, the specification of radiation mutants, and tumor suppressors. It became active through research of Rb, a supperessor. According to cell division control mechanism, which became more detailed in the 1990s, small cell growth regulators regulate cell growth, differentiation, development, aging, and apoptosis through cell growth regulation. Turned out. The results of this study have already helped to better understand the pathological phenomena of various diseases. A representative example is cancer. In the process of transforming normal cells into cancer cells, cell growth regulation is often lost. The analysis of cancer cells showed that the activity of cell growth regulators was often different from normal, and among them, the correlation with invasion / metastasis, which is the most problematic problem in cancer pathology, was shown. In some cases. In addition, cell cycle regulation is abnormal from the fact that inducing overexpression or knock-out of elements regulating cell growth using transgenic animals results in cancer in these animals. deregulation has been shown to be a direct cause of cancer.

세포성장 과정은 여타 모든 생물학적인 조절과 마찬가지로정방향조절(positive regulation)과 역방향조절(negative regulation)을 받고 있다. 현재까지 알려진 세포주기조절의 주골격은 사이클린-의존 키나아제 활성에 의해서 그 진행이 결정되며, 이 키나아제 활성은 세포가 처한 환경에 따라 정방향 또는 역방향 조절을 받게 된다. 많은 암세포나 발암기전의 연구결과 이 정방향 또는 역방향 조절에 문제가 발생되는 경우가 많이 발견되었다. 즉 필요 이상의 지나친 정방향 효과(positive effect) 또는 역방향조절의 상실, 및 이에 의해 세포성장 조절에서 중요한 면인 적절한 조절이 어긋나는 것이 암세포에서 문제점으로 지적되었다.The cell growth process, like all other biological controls, is subject to positive and negative regulation. The main skeleton of cell cycle regulation known to date is determined by cyclin-dependent kinase activity, which is subjected to forward or reverse regulation depending on the environment in which the cell is located. Many cancer cells or carcinogenesis studies have found that this problem occurs in forward or reverse control. In other words, it was pointed out as a problem in cancer cells that excessive excessive effect or loss of reverse regulation, and thereby the proper regulation, which is an important aspect of cell growth regulation, is out of necessity.

포유류에 존재하는 대표적인 사이클린-의존 키나아제는 크게 3 가지로 분류될 수 있다. 첫째는 세포주기의 미드(mid)-G1 상(phase)에서 활성이 있는 CDK4(사이클린-의존 키나아제 4)이고, 둘째는 미드-G1 과 S 상에서 활성이 있는 CDK2, 및 G2-M 상 키나아제인 CDC2(CDK1) 이다. 이중 CDK4 와 CDK2 는 G1-S 세포주기 첵크포인트(check point)에 의해서 그 활성이 조절되며, CDC2 는 G2-M 체크포인트에 의해서 조절되는 것으로 알려져 있다. 여러 암세포들에서 CDK4 와 CDK2, 및 CDC2(CDK1)의 조절기작에 이상이 나타나고 있으며, 실제로 형질전환 동물에서 이들을 인위적으로 비정상적인 상태로 유도하면 암이 유발되는 것으로 입증되고 있다. 이는 여러 사이클린-의존 키나아제 중 CDK4 와 CDK2 및 CDC2(CDK1)가 항암제로서 가장 유망한 표적(target)임을 증명한다고 하겠다.Representative cyclin-dependent kinases present in mammals can be broadly classified into three types. The first is CDK4 (cyclin-dependent kinase 4), which is active in the mid-G1 phase of the cell cycle, and the second is CDK2, which is active in the mid-G1 and S phases, and CDC2, which is a G2-M phase kinase. (CDK1). Among them, CDK4 and CDK2 are regulated by G1-S cell cycle checkpoint, and CDC2 is known to be regulated by G2-M checkpoint. In many cancer cells, the mechanisms of CDK4, CDK2, and CDC2 (CDK1) have been shown to be abnormal. In fact, inducing the artificially abnormal state in transgenic animals has been shown to cause cancer. This suggests that, among other cyclin-dependent kinases, CDK4 and CDK2 and CDC2 (CDK1) are the most promising targets for anticancer drugs.

먼저 CDK4 의 경우를 좀더 자세하게 설명하면, CDK4 활성의 비정상적 조절과 암 유발과의 연관은 여러 암 조직에서 잘 나타나고 있다. 여러 암에서 p16, p15의결실(deletion)이 보고되었고, 특히 사이클린 D1 의 과발현은 여러 암에서 나타나는데 특히 유방암이 전이성질을 띠는 것과 잘 연관되어 있는 것으로 나타나고 있다. 이는 비정상적으로 조절된 CDK4 활성이 암세포의 악성표현형(malignant phenotype)의 요인이 될 가능성을 제시해 주고 있다. p16 녹-아웃 마우스가 p53 녹-아웃 마우스 만큼이나 암을 잘 발생한다고 보고된 것은 p16 의 CDK4 기능 조절의 상실이 암의 원인이 되는 것을 입증하는 것이라고 볼 수 있다. ras 나 src 등을 과발현시킨 NIH 3T3 세포에서는 하부(downstream)에서 그 역할을 수행할 가능성을 보여준다고 할 수 있다. 역으로 p16 이나 p21 을 ras 로 형질전환시킨 변형된 표현형이 정상적인 표현형으로 바뀌는 것이 관찰되었다. 위에 열거된 실험적 증거들은 CDK4 활성의 비정상적인 조절이 암을 유도하는 원인이 됨은 분명한 사실이라는 것을 입증한다고 여겨지고, 더 나아가 암세포의 표현형을 유지하게 하는 역할을 하고 있을 가능성을 보여 준다고 하겠다. 따라서 CDK4 의 저해제는 항암효과를 보일 가능성이 매우 높다고 생각된다,First, the case of CDK4 is described in more detail. The association between abnormal regulation of CDK4 activity and cancer induction is well represented in various cancer tissues. Deletion of p16 and p15 has been reported in several cancers, in particular overexpression of cyclin D1 appears in many cancers, particularly with breast cancer metastasis. This suggests that abnormally regulated CDK4 activity may be a cause of malignant phenotype of cancer cells. It has been reported that p16 knock-out mice are as cancerous as p53 knock-out mice, demonstrating that loss of p16 CDK4 function regulation is responsible for cancer. NIH 3T3 cells overexpressing ras or src show the potential to play its role downstream. Conversely, a modified phenotype transforming p16 or p21 into ras was observed to be normal. The experimental evidence listed above is believed to demonstrate that it is clear that abnormal regulation of CDK4 activity is responsible for cancer induction, and furthermore, may play a role in maintaining the phenotype of cancer cells. Therefore, CDK4 inhibitors are highly likely to have anticancer effects.

다음으로 CDK2 의 경우는 일부 유방암에서 사이클린 E 의 과발현이 관찰되었고 이는 유방암의 전이와 깊은 연관이 있는 것으로 알려져 있다. 사이클린 E 의 과발현이 낮은 혈장조건에서 세포의 소멸을 저해하며, 고정-의존성 성장(anchorage-independent growth)을 유발하는 것으로 제안되었다. MMTV 프로모터(promoter)를 이용한 CDK2 과발현성 형질전환 동물에서는 흉부상피세포의 과증식, 신생물형성이 관찰되었다. 이러한 사실은 CDK2 활성이 세포변형 과정, 또는 그것의 유지에 관여됨을 강하게 시사하며, CDK2 저해제가 항암제로서 높은 이용가능성이 있음을 증명한다고 할 수 있다.In the case of CDK2, overexpression of cyclin E was observed in some breast cancers, which is known to be closely related to the metastasis of breast cancer. Overexpression of cyclin E has been suggested to inhibit cell disappearance in low plasma conditions and to induce anchorage-independent growth. Overproliferation and neoplasia of thoracic epithelial cells were observed in CDK2 overexpressing transgenic animals using MMTV promoter. This strongly suggests that CDK2 activity is involved in the process of cell transformation, or maintenance thereof, and proves that CDK2 inhibitors are highly available as anticancer agents.

이밖에도 CDC2(CDK1), CDK3, CDK5, CDK6, CDK7 등도 세포분열 과정의 각 단계에서 중요한 역할을 하고 있는 것으로 속속 밝혀지고 있으며, 같은 사이클린-의존 키나아제(CDKs)의 부류로 구분되고 있다. 또한, 사이클린의 부류에는 위에서 언급했던 사이클린 D1 이나 사이클린 E 이외에 사이클린 A, B, C, D2, D3, D4, F, 및 사이클린 G도 포함된다.In addition, CDC2 (CDK1), CDK3, CDK5, CDK6, and CDK7 have been found to play an important role in each step of the cell division process and are classified into the same cyclin-dependent kinase (CDKs). The class of cyclines also includes cyclins A, B, C, D2, D3, D4, F, and cyclin G in addition to cyclin D1 or cyclin E mentioned above.

이렇게 축적된 연구결과들을 바탕으로 하여 항암제의 좋은 표적으로서 이들 사이클린-의존 키나아제(CDKs)들을 효과적으로 억제하는 저해제를 개발하고자 하는 연구가 최근에 와서 이루어지기 시작하였다.Based on these accumulated findings, research has recently begun to develop inhibitors that effectively inhibit these cyclin-dependent kinases (CDKs) as good targets for anticancer drugs.

지금까지 효과적인 CDKs 저해제로서 개발된 대표적인 화합물로는 하기 화학식 4 의 플라보피리돌[Flavopiridol; 유럽특허 제 0,241,003 호(1987) 및 제 0,366,061호(1990)]을 들 수 있다.Representative compounds that have been developed as effective CDKs inhibitors to date include the flavopyridols [Flavopiridol; European Patent Nos. 0,241,003 (1987) and 0,366,061 (1990).

그 다음으로 하기 화학식 5로 표시되는 퓨린 구조를 갖는 CDKs 저해제가 최근에 보고되었다(참조: WO 97/16447).Next, CDKs inhibitors having a purine structure represented by the following formula (5) have recently been reported (see WO 97/16447).

[화학식 5][Formula 5]

상기한 바와 같이 지금까지 몇가지 CDKs 저해제가 개발되었지만, 아직까지 충분히 만족스러운 화합물은 개발되지 못하였다.As described above, several CDKs inhibitors have been developed so far, but no sufficiently satisfactory compounds have yet been developed.

이에 본 발명자들은 이들 CDKs 효소들의 저해제에 대하여 광범하고 집중적인 연구를 수행하였으며, 그 결과 지금까지 알려진 CDKs 저해제들의 구조와는 전혀 다른 구조를 가지는 상기 정의된 화학식 1 의 나프토퀴논 계열의 화합물이 CDKs 효소들을 효과적으로 저해함을 확인하고 본 발명을 완성하게 되었다.Accordingly, the present inventors have conducted extensive and intensive studies on inhibitors of these CDKs enzymes. As a result, the naphthoquinone-based compound of Formula 1 defined above has a structure that is completely different from the structures of CDKs inhibitors known to date. It was confirmed that the enzymes effectively inhibited and the present invention was completed.

따라서, 본 발명의 목적은 신규한 사이클린-의존 키나아제 저해제(CDKs 저해제) 화합물 및 그의 제조방법을 제공하는 것이다. 여기서 CDKs 란 CDK2, CDK4 및 CDC2 (CDK1), CDK3, CDK5, CDK6, CDK7 등을 모두 포함하며, 사이클린도 사이클린 D1 과 사이클린 E 및 사이클린 A, B, C, D2, D3, D4, F, G를 모두 포함한다.Accordingly, it is an object of the present invention to provide novel cyclin-dependent kinase inhibitor (CDKs inhibitor) compounds and methods for their preparation.
